The Lowdown
Alright folks, Rusty here. Let's get into it, just the local picture for Jaconé. We've got a bit of a wait on our hands, but the second half of the outlook is where the real action is.
The first week is a bit of a mixed bag, with small, inconsistent energy and a lot of iffy wind. The water is sitting at a pretty normal 72°, nothing unusual there. Don't get your hopes up for the weekend of the 25th. Saturday morning offers some knee-to-waist high, 5 ft swell from the south with a 10-second period. The wind is cross-off from the NNE, but the wave energy is moderate (444). It's surfable, but not a standout. It gets messy from there. Sunday the 26th has a long-period (14-second) south swell at 3 ft, but the cross-on wind ruins it. Monday the 27th morning is clean with offshore ENE wind, but the swell is only 3 ft and the energy is weak (386). The rest of the week is a frustrating grind of small, weak swells and poor conditions or onshore winds.
Hold on. The real promise starts to build on the 1st of August. Saturday morning the 1st brings a clean 4 ft south swell with offshore NE wind and moderate energy (424). It's a taste of what's coming.
Then we hit the prime window. Tuesday the 4th of August is your best bet. The morning session at Jaconé is going to be class. A clean 5 ft south swell with a 11-second period, offshore NE wind, and strong wave energy (675). This is the pick of the entire forecast. The conditions are spot on for experienced intermediates. The morning is the call, as the afternoon gets a bit of a cross-off breeze.
The week of the 5th gets bigger, but it's for the experts. Thursday the 6th of August morning sees a solid 8 ft east swell, but the period is a short 9 seconds, making it a bit of a grindy wall. The wind is offshore from the NE, and the energy is very strong (1235). This is a serious, powerful wave and only for experienced surfers. The afternoon gets blown out by a strong 30 km/h east wind.
The following Sunday the 9th of August morning is another excellent call. The swell is a solid 7 ft from the ENE with an 8-second period, a bit short, but the offshore NE wind at 15 km/h will keep it clean. The wave energy is very strong (813), making for some punchy, powerful waves. Again, this is for the more experienced crew.
So, to sum it up: the first week is a wash. The window opens on the 1st of August, but the two true standouts are the morning of the 4th (best for most) and the morning of the 9th (for the experts). Get out there.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
